OLED display device having touch sensor and method of manufacturing the same

An organic light emitting diode (OLED) display device having a substrate on which organic light emitting diodes (OLEDs) and a passivation film for protecting the OLEDs are formed, and a touch sensor disposed on the substrate, the touch sensor comprising:

• a base layer having a first outer surface and a second outer surface that are opposite to each other;
• a plurality of first touch electrodes arranged directly on the first outer surface of the base layer;
• an inorganic layer directly on the second outer surface of the base layer;
• a plurality of second touch electrodes arranged directly on the inorganic layer in a direction perpendicular to the first touch electrodes;
• a plurality of first routing wires connected to the plurality of first touch electrodes on the first outer surface of the base layer, respectively;
• a plurality of second routing wires separated from the plurality of first routing wires and formed on the first outer surface of the base layer;
• and
• a plurality of third routing wires connected to the plurality of second routing wires respectively via holes that pass through the base layer, and formed on the second outer surface of the base layer,
• wherein the base layer is one of a barrier layer, an anti-scratch layer, and a circular polarization layer.
